Watch DesignBrain AI work live

DesignBrain AI

It works like a teammate.

Ask for a flowchart and watch a cursor glide across the board, placing real shapes you can edit. Stop it or undo it at any time.

Canvas

Fast as your thinking.

Sticky notes, smart connectors, frames, and pages. Paste text or raw script to get editable diagrams instantly. Export cleanly when you finish.

Collaboration

One board, everyone on it.

Live cursors, shared selection, and read only links for anyone. Up to 25 people on a board at once.

LLM attention mechanism

DesignBrain AI

Brainstorm, prompt, or refine. Map complex ideas faster together.

DesignBrain AI is a fluid co-creator built directly into your diagramming canvas. Drop sticky notes, map out rough shapes, or generate complex workflows from a simple sentence. The AI instantly analyzes structural relationships to route connectors, format layouts, or convert raw data into clean visual flows. It joins your board as a visible cursor working alongside you, leaving you in absolute control to edit, style, or undo any action instantly.
